THERMOSTAT/REMOTE SENSOR QUICK REFERENCE
Before operating the thermostat, familiarize yourself with the display and button functions. Both thermostat and remote sensor consist of two parts: the cover and the base. To remove a cover, pull it straight out from the base. To replace a cover, line it up with the base and press until the cover snaps into place on the base.
The Thermostat Buttons and Switches and Display
1Raises and lowers the temperature setting.
2Light flashes every 20 seconds indicating acceptable signal reception from indoor or outdoor remote sensor.
3Buttons for setting time (Time), programming (Prgm), running program (Run) and bypassing program to hold a constant temperature (Hold).
4SYSTEM button (COOL, AUTO, HEAT, OFF, EMER heat pump systems only).
5FAN switch (ON, AUTO).
6Displays the active temperature sensor (outside, remote, local) and its sensed temperature.
7Displays ( ) when in keypad lockout mode.
8Indicates day of the week.
9Indicates the thermostat mode information:
"HOLD" alternates with the system mode (see item 12) if the HOLD button is pressed to bypass the program and maintain a constant temperature.
10Displays currently programmed set temperature (blank when SYSTEM is OFF).
11Alternately displays the current time and the tempera- ture average of sensors (thermostat [local] and/or indoor remote) turned on.
12"HEAT" is displayed when set to heating, "COOL" is displayed when set to cooling,
"AUTO" is displayed when set for automatic change- over between heating and cooling.
When "AUTO" is displayed, the currently active mode (Heat or Cool) will also display.
"EMER" is displayed flashing (heat pump systems only) when the thermostat is set to the Emergency Mode. Emergency is used to bypass the heat pump and use only the
"FLTR" is displayed as a reminder to change or clean the air filter after system has run for the programmed filter time period.
13Stage 1 & 2 indicator.
"STG 1" indicates when the first stage heat or cool is energized. "STG + 2" indicates when the second stage heat or cool is energized. "+2" blinking indicates Auxiliary Heat stages are energized on Heat Pump Systems.

Figure 7 – Thermostat display, buttons and switches
14Displays "LR" when the limited range feature is activated. Limited range limits the temperature the thermostat can be set to.
15Indicates the system is sending a fault signal to the thermostat "L" terminal. This does not indicate a fault in the thermostat.
16Antenna will display for a few seconds when the remote or outdoor transmitted signal is received.
17Displays "LOW BATT" when the 2 "AA" batteries are low and should be replaced.
18Indicates the current signal strength level of the remote temperature system. Signal strength level is low (one bar on), medium (two bars on) or high (three bars on). The remote will operate with 1 bar showing.
